Late today I had near perfect weather conditions for doing a little experiment: light north winds, which are blocked by a ridge and tree line that runs along the north side of my usual "test" road, leaving the road in nearly still air.

Is there anyway you could have side mirrors on the inside of the car that still function?

Yep! You're right! Side mirrors on the INSIDE are the only way to go! The little round "stick-ons" , stuck to a piece of bent aluminum...stuck in a seam or crack in the dashboard cover. I've been doing this for years...and fighting with auto inspection people for years, too! Hey! Rear-view is rear-view...even thru the glass! The only requirement? They must be convex...to 'see' around your window post (right side only). Depth perception is a problem ("How fast is he coming up alongside?"), but a quick check of the (flat) rearview mirror over the windshield will confirm this. Hint: If ANYTHING is in your right-side convex...don't go there!!! -Ted Hart
